Description

Rich and honour banyan scale cuttage and quick-propagation seedling-cultivating method

Technical field

The present invention relates to technical field of plant asexual propagation, be specially rich and honour banyan [Ficus altissimacv.'Yellow Gem'] cuttage and seedling culture method.

Technical background

Rich and honour banyan, also known as gold leaf banyan, Ma Rong etc., is Moraceae Ficus, perennial Chang Muben ornamental foliage plant.Originate in the ground such as Chinese Hainan, Guangxi, Yunnan, India, Southeast Asia.Its property happiness high temperature and humidity weather, drought-resistant barren, wind resistance, anti-atmospheric pollution.Impoverishment tolerant and arid, wind resistance and anti-atmospheric pollution, growth rapidly, is transplanted and is easily survived.Rich and honour banyan blade scatters yellow patch, beautiful in colour, be suitable for row view seeds.Quite like by consumers in general, market increases for the demand of rich and honour banyan high quality seedling is anxious.Accelerate rich and honour banyan industry development, set up large-scale production base, keep the various merit of the excellent maternal plant of rich and honour banyan genetic stability in offspring individuals, improve survival rate, realize rich and honour banyan seedling industry production key technology.

At present, industry adopts normal cutting propagation cultivating method in the production of rich and honour banyan, the cutting medium adopted is domestic peat soil, and otch is also without disinfecting, and the kind shoot survival percent of cuttage under this mode is below 20%; Conventional high-pressure breeds its survival rate also lower than 30%, and these greatly reduce reproduction speed, is unfavorable for that seedling is produced in industrialization.

Summary of the invention

The object of this invention is to provide a kind of rich and honour banyan scale cuttage and quick-propagation seedling-cultivating method, its cuttage survival rate is high, and growth cycle is short, and production cost is low, can a large amount of rich and honour banyan seedling of Fast-propagation.

To achieve these goals, the present invention adopts following technical scheme:

Rich and honour banyan scale cuttage and quick-propagation seedling-cultivating method, realizes as follows:

(1) seedbed and matrix prepare: seedbed adopts greenhouse seedbed, ensures ventilated; Matrix adopts volume ratio to be the mixture of the peat soil of 8-10:1-2:0.5-1, river sand and active carbon; Matrix is contained in seedling-cultivating tray, seedling-cultivating tray is placed in seedbed, within 1-3 days before cuttage, doubly matrix is irrigated for subsequent use with large raw 800-1000;

(2) cutting selected with prune: select annual and lignification, leaf look yellowish green alternate, the rich and honour banyan branch that has maternal character without damage by disease and insect; Cutting 10-15cm stem section is cutting, each cutting has 1-2 to open blade, and blade is cut off 2/3, and the lower cut of cutting is miter angle scarf, the upper cut truncation of cutting is also stained with paraffin, loads freshness protection package moisturizing for subsequent use after upper and lower otch juice is dry by cutting;

(3) root is urged in cutting: by the lower cut 3000-5000 of cutting times of potassium permanganate cleaning after 3-5m minute, slightly drain open fire, then the mixed liquor lower cut of cutting being put into 100-200ppm 1-naphthalene acetamide and 100-300ppm plant hormone IBA soak 5-20 clock after namely can be used for cuttage;

(4) cutting cuttage: in the usual way cuttage is carried out to cutting;

(5) maintenance: keep temperature 25-30 DEG C, first half of the month light intensity 10-30umolm ^-2s ^-1, light intensity 50-80umolm after two weeks ^-2s ^-1, light intensity 80-250umolm after 4 weeks ^-2s ^-1; Whole maintenance processes relative moisture controls, at 80-95%, suitably to ventilate, and will spray 1-3 blade face water guarantee cutting not dehydration every day; 3-4 girth root after inserting, 4-5 week sprouting starts to grow, and about 6-7 week grows up to whole plant.

Above-mentioned seedbed is movable seedbed.

After adopting such scheme, compared with prior art, tool has the following advantages in the present invention:

One, in the present invention, annual and lignification, leaf look yellowish green alternate, the rich and honour banyan branch that has maternal character without damage by disease and insect is selected in cutting, after inserting, the performance characteristic of branch is consistent with former female parent, can not variation be caused, there will not be full Huang, the entirely not obvious situation of green or patch.

Two, the present invention adopts peat soil, river sand, active carbon is as cutting medium, one is ensure that socket end matrix is moistening and ventilative, add the harmful substance that active carbon is absorption wound, hestening rooting, peat soil moisture capacity is strong, the growing environment that branch is preferably can be provided, protect the demand into normal long root.

Three, selected select lignification current-year branch, the lower cut of cutting be miter angle scarf with shearing procedure in cutting, upper cut truncation and otch is stained with paraffin, and guarantee cutting not dehydration divides, and has activity.Cutting is urged in root step, and first hinder lower cut with 3000-5000 times of potassium manganate cleaning, be sterilization on the one hand, be also antioxidation simultaneously, and protection lower cut has activity; Use the 1-naphthalene acetamide of 100-200ppm and the plant hormone IBA immersion treatment of 100-300ppm again, object is the long root in growth-promoting lower end, improves cuttage survival rate.

Four, utilize different light intensity changes, stable temperature and ventilative seedbed, improve plantation survival rate;

Five, employing activity seedbed, such conveniently moving, can be mobile with the long distance of seedling-cultivating tray after cuttage seeding survives, and ensures that seedling survives the sale transport in later stage, shorten potted plant supply of material implantation time.

The cuttage survival rate of the inventive method reaches more than 90%, and growth cycle is short, and production cost is low, can a large amount of nursery stock of Fast-propagation, to meet the demand in Afforestation Landscape market.
